Carrier/rack problems of the 2012 Chevrolet Traverse

I was driving at about 50mph the check traction control lights came on the check stabilitrack came on then it said traction control on then off my vehicle lost power and I couldnt steer. Luckily no cars were coming on the dark winding road I was on as I was stuck no lights or anything.

I have a 2012 chevy Traverse, ive only owned it less than 2 years and had issues with service stabilitrack/traction control at least 6 times. When this happens the car looses power, my check engine light comes on, ive even had black smoke come out of my hood and tail pipe trying to keep it running on the highway so my family and I werent killed. I have taken it to the dealership and the codes it throws makes no sense . After they wipe the codes, let it sit its fine for a few weeks. I know im not the only Traverse owner with this issue, is it going to take a family dying on a major highway, or a child being killed because their parents lost power in their only car in traffic and a truck hit them. Please please fix this issue. I dont wanna die because I bought a Traverse. I cant afford another car payment right now.

I was driving through a parking lot and the stabillitrack light came on, the check engine light flashed and the traction control light came on. The driver center said the traction control shut off and it also stated to service stabillitrack. The engine seemed to slow itself as well. I parked the vehicle and waited a few minutes. The warning lights finally went off on their own and the traction control turned back on, on it's own. The car seemed ok driving home for 2 miles and engine power seemed to return to normal but there seems to be some hesitation in the transmission shifting at low speeds too. I called the dealer and the soonest they can get me in to check the car is Monday. I asked if it was safe to drive and they would not commit to safety or reliability but refused provide any relief until Monday and gave me no offer of a loaner car. I just did some investigating online to research what the cause of this problem might be and it appears that this is a very common problem with this vehicle and it can occur at high speeds on the highway. Many forums list many people with this complaint. I am concerned this could occur again and cause an accident. The problem looks to be intermittent and will occur without warning at any speed. In my opinion this is a safety problem which needs to be taken seriously. I am fearful for my families safety in this vehicle.
